How to Handle RC 8/RC 12/ RC 16 TR's in CHARM?

Hi Experts,

We are coming across a scenario, where in there are TR's which are imported with RC 8/RC 12/ RC 16. To overcome this issue user create one more Bug Fix TR and fix the same. But in ChaRM user is not able to proceed as it blocks the user at Sucessfully Tested status. ChaRM in Backend tries to re-import those TR's with error.
